T0 all 'whomit may concern:

Be it known that we, CHARLES H. OVERLY and OWEN A. THOMPSON, citizens of the United States of America, residing at Independence, in the county of Montgomery and State of Kansas, have invented certain new and useful Improvements in Pulling- Machines, of whichpthe following is a speciication.

The present invention relates to improvements in pulling machines to be used for the purpose of pulling rods from bored wells.

The primary object of the invention is to provide improved means for raising the rods or tubes when it is necessary to connect more tubes or rods for the purpose of placing them in the well, by providing a mechanical lift to release the elevator from under the lmuckle of the tube or rod, after the tubes have been hoisted by the hoisting machine, and the invention is further designed to provide certain other improvements as will be apparent from the drawings.

The invention consists in certain novel combinations and arrangements of parts as will be hereinafter morefully described and claimed.

In the accompanying drawings we have illustrated one lcomplete example of the physical embodiment of our invention constructed according to the best mode we have so far devised for the practical application of the principles of the invention.

Figure l is a side elevation of a machine embodying the novel features of our invention. F ig. 2 is a front view of the lower portion of the pulling machine of Fig. l. F ig. 3 is a view showing detached, the actuating parts of the pulling machine.

In the preferred embodiment of our invention the pulling machine comprises a mast which includes two side arms 1 1 which are suitably connected and braced, and at their bottoms are joined by the large beams 2 2. At the upper end of the mast the usual wheel or pulley 3 is journaled, and when the mast is in working position, as shown in Fig. 1, suitable guy ropes (not shown) and braces are employed to hold the mast in position.

The hoisting mechanism of the machine includes a reel 4 supported on the horizontal shaft 5, between the two arms 1 1 and the shaft 5 is journaled in bearings in two upright posts 6 6 that are secured each at the inner sides of the arms 1 1 and bolted to the cross beams 2 2. In connection with the reel l a pair of brake drums 7 7 are employed, and additional reels 8 8 are provided between these two drums over which the power rope 9 may be wound. The central reel 4 is for the pull rope 10 which is woimd upon the reel, and extends up over the pulley 3, and by means of a hook 11 is adapted to engage the bail or eye 12 of the elevator 13 which is connected, as in F ig. 1 to a lifting tube 14. A

Each of the brake drums 7 7 is provided witha brake band as 15 15, and each of these bands is connected to a crank shaft 16 which is journaled in bearings 17, bolted toone of the beams 2. One end of each of the bands, as 1S, is fastened as by bolts 19 to the front beam 2, and the free end of each band 15 is swiveled or journaled on the crank shaft 16, as at 20. Thus, it will be understood that the brake bands have their forward ends anchored or attached to the front beam by the bolts 19, and their rear or free ends are loosely connected with the crank shaft, it being of course understood that the bands pass over the drums l7, and are adapted to frictionally contact therewith. Thus, by movement of the crank shaft, the brake bands are applied to the drums, and the reels or hoisting mechanism are controlled.

The operating lever 21 which is journaled in brackets 22 fixed to the front of the beam 2, has a shorter arm 23 extending back through the mast toward the crank shaft, and this short arm of the lever is'linked to the crank shaft by means of the link 24:. In

Fig. 3, all the actuating parts are shown in full lines, and it will be apparent that when the lever 21 is thrown to the left, the movement of the arm 23, link 24, and crank shaft 16, will apply the brake bands to the brake drums to control the rotation of the reels.

In connection with the braking mechanism we employ vertically slidable, or movable bearings for the hoisting device. In the drawings it will be seen that the shaft 5 is journaled in heads 25, which are slidable in the brackets 26, and each of these heads 25 has link 27 pivoted thereto, which links are connected by the cross bar 2S which is joiirnaled in the brackets 29 secured to the posts 6*(3. rlhis cross bar 28 insures that the tivo bearing heads .25 shall move oi" slide in unison. The cross bar 28 is in reality a, rock bai, and it is rocked from the crank sliait 1G, the bar and shaft being connected by a link 28 which is slotted and loosely pivoted or joiirnaled to each bar. Thus, it Will be seen from the inspection of Fig. 3, that ivhen the operating lever 2l is moved to the leit, the connecting links Will be actuated so that the journal bearing head Will be caiised to .move downwardly in the direction olf the aii'oii, and thus move the reel and driiins with it. The parts are returned to their normal position in Figs. l and 3, by the reverse movement oiLl the lever '21, and the load on the driiins and reel, hold the device in the Upper normal position.

ln iise, assuming` that the elevator is placed under a knuckle of a rod, for the purpose oit' holding' the rod and connecting more rods to be placed in the Well, after siicli additional rods are connected up, they are `held by the elevator which rests iipen the top ot the Well casing, and in oider to disengi'age and free the Ylevato? from the knuckle, it is neces f 'o litt this Weight a slight distance to releafx, the elcvatoi'. rlliis lifting is accomplished by a continuation of the leveil movement which applies the brake to the di inns, to the left in Fig. 3, and it Will be seen that the reels are under the control oif the operator vvhile this lifting movement is going on, and the lifting nieve nient is a complished by the bodily doivn- .vai'd n'ioveinent ot tie drums and reel. The iise oit those slidable journal bearings for the driiins obviates the necessity for maniially operating the brake drinne to give this lift, Which is known as the kick oil'.77

Having thiis i'iilly described oiir invelition, what ive claim as nevv and desire to seciire by Letters Patent, is 2 l. rllie combination in a pulling machine with its mast and Winding mechanism, of movable journal supports for said Winding mechanism, braking means for the Winding; mechanism, and means connected with the braking; means for bodily moving the Wind* ing mechanism in its journal bearings.

2. The combination in a pulling machine Vvidi its mast of a Winding,` drinn and its brake and movable journals for said drinn, means ior actiiai'giiip,` the brake, and connections from said actuating means adapted to bodily nieve the Winding drinn after the brake has been applied.7 p

8. rilhe combination in a pulling machine ivith its mast, of a Winding` device supported in movable bearings, braking mechanism, the opeiating lever for said braking ineclianism, a rock bar actuated trein the operating` lever, and links connecting` said bar with the movable Winding mechanism.

et. The combination. in a pulling` machine With its mast, of a Winding mechanism inevably supported on said mast and including brake drums, inea-ns i'ior braking said di'iinis,

et slidable bearings for the Winding` 'li lism, a rock bar connected with said ms, and connections between said rock i the brake operating mechanism.

ln testimony whereof We affix oin1 signs tiii'es in presence oi two Witnesses.
